    W32: Override libtool internal variables to produce a delay-load import library
    
    We remove --out-implib, add --output-def (where needed), and add extra call
    to dlltool to generate delay-load import library (name's the same as normal
    import library, so tools/applications won't notice the change).
    When application is linked to libgedit via such import library, the DLL is
    only loaded when first function from it is called. This gives us time to
    influence W32 runtime linker.
